You can disregard anything Simpson says, he is an habitual liar.
Example from today:
Derek Simpson, co-leader of Unite, again accused the airline of imposing changes on cabin crew without their agreement. He said his union negotiators had come within £10 million of the savings sought by BA - a "drop in the ocean" compared with today's losses.
Not even the fictitious figure they first came out with was close - because it was only temporary and they wanted it back.
This ridiculous old fool should just retire.
